Warning! Disconnect from power and allow to cool before cleaning.
To clean the fixture:
1. Disconnect the fixture from power and allow it to cool for at least 10 minutes.
2. See Figure 7. Unclip and remove the head air filter from the center of the lens plate. Rinse the filter in
lukewarm soapy water and blot dry. If the filter is not in perfect condition, replace it with a new one
(available from Martin, P/N 62407156).
3. Vacuum or gently blow away dust and loose particles from the outside of the fixture and the air vents at
the back and sides of the head and in the base with low-pressure compressed air.
4. Clean the front glass by wiping gently with a soft, clean lint-free cloth moistened with a weak detergent
solution. Do not rub the surface hard: lift particles off with a soft repeated press. Dry with a soft, clean,
lint-free cloth or low-pressure compressed air. Remove stuck particles with an unscented tissue or
cotton swab moistened with glass cleaner or distilled water.
5. Reinstall the head air filter.
6. Check that the fixture is dry before reapplying power.
7. Using the
INFO-AIRF-TOTL
control menu, reset the counter for elapsed time in hours since the
fixture was cleaned to

by displaying the counter and pressing and holding the up button for five
seconds.
Removing and installing head modules
From software version 1.2.0 (available for download free of charge from www.martin.com for fixtures with
earlier software versions), two head modules can be installed and controlled in the MAC 401™.

from power and allow
to cool for at least 10
minutes.
Torx 30 screwdriver to
release the four head
module retaining
screws (arrowed), lift
the module away from
the yoke slightly,
disconnect the head
module safety wire and
lift the module away
from the head.
3. Head module
installation procedure
is the reverse of the
removal procedure.

installing a module, clip
the safety wire into the
attachment point in the
yoke frame, and make
sure that the
connectors in the
module engage in the
connectors in the yoke
frame while you press
the module into
position on the head.

automatically senses
which modules are
installed when power is
